pulp vat. Paper pulp was placed in the vat and mixed with
a lot of water. The water was then drained and the pulp
fibers were poured out of the vat and onto a conveyor belt.
The conveyor belt took them under the rollers. There were
quite a lot of rollers as you can see. These rollers smoothed
the fibers and pressed them dry. The finished paper was
then put on a roll at the end. You can see the roll of paper at
